[0006] Problems to be solved by the invention
[0007] A plurality of trays are stacked and arranged in the tray storage unit disclosed in Patent Document 1.

[0032] (Implementation Method)
[0033] [structure]
[0034] First, the structure of the component supply device according to the embodiment will be described.
[0035] Figure 1 It is a top view which shows the component mounting system 10 which concerns on embodiment. Figure 2 It is a perspective view showing the component supply device 100 according to the embodiment. Figure 3 1 is a block diagram showing the functional structure of the component supply device 100 according to the embodiment. Figure 1 as well as Figure 2 In the figure, illustration of a computer for controlling each device included in the component mounting system 10, such as the control device 170, is omitted.
[0036] The component mounting system 10 is a system for producing a mounting substrate on which components are mounted by mounting components on a substrate 400 .
[0037] As the substrate 400 , a film-shaped flexible substrate formed of a resin or the like is exemplified. In addition, the substrate 400 may be a rigid substrate such as a glass substrate.
[0038] As components bonded to the substrate 400 via the ACF slice, electronic components such as IC (Integrated Circuit), TCP (Tape Carrier Package), and FPC (Flexible Printed Circuits) are exemplified.
[0039] The component mounting system 10 includes a component mounting device 200 and a component supply device 100. For example, the component mounting system 10 includes an ACF (Anisotropic Conductive Film) pasting device (not shown) located upstream of the component mounting device 200 and a final pressure bonding device located downstream of the component mounting device 200.
[0040] The ACF attaching device receives the substrate 400 carried in from the loader and attaches the ACF as an adhesive member to the electrode portion of the substrate 400. The ACF attaching device is realized by, for example, a conveying mechanism for conveying the substrate 400 and an attaching mechanism for attaching the ACF to the substrate 400.
[0041] The component mounting device 200 is a mounting device for mounting components on the substrate 400. Specifically, the component mounting device 200 temporarily presses the components to the substrate 400. More specifically, the component mounting device 200 temporarily presses the components supplied from the component supply device 100 to the portion of the substrate 400 carried in from the ACF pasting device to which the ACF is pasted.
[0042] The component mounting device 200 includes a component placement table 220 , a component mounting section 230 , a substrate stage 240 , and a substrate conveying section 250 .
[0043] The component placement table 220 is a table on which components picked up by the component pickup unit 190 and supplied from the component supply device 100 are placed. Specifically, components that were placed on the tray 300 and picked up by the component pickup unit 190 are placed on the component placement table 220 .
[0044] The component mounting section 230 is a device that picks up a component mounted on the component mounting table 220 and mounts (more specifically, temporarily press-bonds) the picked-up component on the substrate 400 mounted on the substrate stage 240 .
[0045] The component mounting portion 230 is realized by, for example, a pickup head for picking up a component and mounting it on the substrate 400, a camera for determining the placement position of the component on the substrate 400, and a support table for supporting the end of the substrate 400 from below. It should be noted that the method for holding the component of the pickup head is not particularly limited, but in the case of this embodiment, as a method for the pickup head to pick up the component, a method for holding the component by vacuum adsorption is adopted. In addition, for example, the pickup head is configured on a head transfer mechanism composed of, for example, a combination of a linear guide and a linear motor, so that it can move.
[0046] The substrate stage 240 is a stage on which the substrate 400 carried in by the substrate conveying unit 250 is placed.
[0047] The substrate transporting unit 250 is a device that carries the substrate 400 from the ACF pasting device to the substrate stage 240 and carries the substrate 400 with components mounted thereon out to the formal crimping device. The substrate transporting unit 250 is realized, for example, by a suction nozzle that absorbs and holds the substrate 400 and a suction nozzle transfer mechanism that moves the suction nozzle. It should be noted that the method of holding the substrate 400 based on the suction nozzle is not particularly limited, but in this embodiment, as a method of holding the substrate 400 by the suction nozzle, a method of holding the substrate by vacuum suction is adopted. In addition, for example, the suction nozzle transfer mechanism is composed of, for example, a combination of a direct-acting guide and a linear motor.
[0048] The final crimping device is a device that performs a final crimping operation of final crimping (i.e., hot crimping) the component temporarily crimped to the substrate by the component mounting device 200 to the substrate. In this way, the electrode portion formed on the substrate and the component are electrically connected via the ACF. In other words, through this final crimping, the component is mounted on the substrate, thereby producing a mounted substrate.
[0049] In addition, each device of the component mounting system 10, such as the component mounting device 200, the ACF pasting device, and the formal crimping device, is controlled by a computer. The computer is implemented, for example, by a communication interface for communicating with these devices, a non-volatile memory storing a program, a volatile memory as a temporary storage area for executing the program, an input / output port for sending and receiving signals, and a processor for executing the program. The communication interface can be a connector for connecting a communication line for wired communication, or a wireless communication circuit for wireless communication. In addition, the computer can be implemented by a single computer together with the control device 170 of the component supply device 100, or by a computer different from the control device 170.
[0050] The component supply device 100 is a device for supplying components to the component mounting device 200. Specifically, the component supply device 100 supplies components to the component mounting device 200 by placing the components on the component placement table 220 using the component pickup unit 190. One or more components are placed on the tray 300, and the one or more components are sequentially picked up by the component pickup unit 190. It should be noted that the type and quantity of components placed on the tray 300 are not particularly limited.
[0051] The component supply device 100 includes a tray supply unit 110 , a sensor unit 120 , a paper pickup unit 130 , a tray conveying unit 180 , a component pickup unit 190 , a collection unit 160 , and a control device 170 .
[0052] The tray supply unit 110 is a device that supplies a tray 300 on which components and a release paper 310 covering the components are placed. In the present embodiment, the tray supply unit 110 supplies the tray 300 to the tray conveying unit 180. Specifically, the tray supply unit 110 supplies the tray 300 by placing the tray 300 on the tray stage 150 provided in the tray conveying unit 180.
[0053] In addition, the empty tray 300 after the parts are picked up is returned to the tray supply unit 110. The tray supply unit 110 is implemented by a storage warehouse (tray storage warehouse) for storing the trays 300. In the storage warehouse, for example, a plurality of trays 300 each carrying a release paper 310 are arranged in an overlapping state. The lower part of the storage warehouse serves as an openable and closable door portion. The trays 300 are delivered by opening and closing the door portion.
[0054] It should be noted that the mechanism for causing the tray supply unit 110 and the tray stage 150 to transfer the tray 300 may be provided in the tray supply unit 110 or in the tray transport unit 180 .
[0055] The sensor unit 120 is a sensor for detecting the presence or absence of the release paper 310 on the tray 300. In the present embodiment, the sensor unit 120 is a camera that photographs the tray 300 from above. The type of sensor used as the sensor unit 120 is not particularly limited as long as it can detect the presence or absence of the release paper 310 on the tray 300, and can be implemented by a sensor that emits light and detects the reflected light of the light at an object.
[0056] It should be noted that, in the following description, the sensor unit 120 is described as a camera.
[0057] The paper pickup unit 130 is a device that picks up the release paper 310 on the tray 300 supplied from the tray supply unit 110 .
[0058] Figure 4 1 is a side view showing the paper pickup unit 130 according to the embodiment.
[0059] The paper pickup unit 130 includes one or more suction nozzles 131 , a support body 132 , and a lifting mechanism 133 .
[0060] The suction nozzle 131 is a nozzle that sucks and holds the release paper 310. The paper pickup unit 130 picks up the release paper 310 on the tray 300 by, for example, performing suction from the suction nozzle 131 while the suction nozzle 131 is kept away from the release paper 310. In the present embodiment, as a method for the suction nozzle 131 to hold the release paper 310, a method of holding the substrate by vacuum adsorption is adopted. It should be noted that the method of holding the release paper 310 by the suction nozzle 131 is not particularly limited. The suction by the suction nozzle 131 may also be started in a state where the suction nozzle 131 is in contact with the release paper 310.
[0061] In this embodiment, the paper pickup unit 130 includes four suction nozzles so as to be able to suck the four corners of the rectangular release paper 310. The number of suction nozzles 131 included in the paper pickup unit 130 may be one or more than two, and is not particularly limited.
[0062] The support body 132 is a support body for supporting one or more suction nozzles. The support body 132 supports the one or more suction nozzles 131 so that the lower surfaces of the one or more suction nozzles 131 (that is, the positions where the release paper 310 is sucked) are at the same height.
[0063] The lifting mechanism 133 is a device that lifts up and down the support body 132 to lift up and down the one or more suction nozzles 131. For example, the lifting mechanism 133 is realized by a cylinder for moving up and down, an air supply source for driving the cylinder, and a valve.
[0064] It should be noted that the structure for moving the suction nozzle 131 is not particularly limited and can be achieved by a motor or the like.
[0065] The tray transport unit 180 is a device that transports the tray 300 .
[0066] The tray transport unit 180 includes a transport unit 140 and a tray stage 150 .
[0067] The conveying unit 140 is a conveying mechanism for conveying the tray 300 placed on the tray stage 150 by moving the tray stage 150. In the present embodiment, the conveying unit 140 moves the tray stage 150 in the X-axis direction and the Y-axis direction. The conveying unit 140 is realized by, for example, a linear guide and a linear motor.
[0068] The tray stage 150 is a stage on which the tray 300 is placed. In the present embodiment, two trays 300 can be arranged side by side in the X-axis direction on the tray stage 150. The number of trays arranged on the tray stage 150 may be one or more, and is not particularly limited.
[0069] For example, the tray transport unit 180 receives the tray 300 on which the release paper 310 is placed from the tray supply unit 110, and transports the tray 300 to a position where the paper supply pickup unit 130 picks up the release paper 310 on the tray 300. In the present embodiment, the tray transport unit 180 moves the tray stage 150 below the tray supply unit 110, and receives the tray 300 on which the release paper 310 is placed from the tray supply unit 110. In addition, for example, the transport unit 140 transports the tray 300 on which the release paper 310 is placed to a position where the component pickup unit 190 that supplies components to the component mounting device 200 picks up the components placed on the tray 300. Thus, the component supply device 100 supplies the components to the component mounting device 200. In addition, when the components are picked up and the tray 300 becomes empty, the tray transport unit 180 moves the tray stage 150 below the tray supply unit 110, and returns the tray 300 to the tray supply unit 110.
[0070] The recovery unit 160 is a mechanism for recovering the release paper 310 picked up by the paper pickup unit 130. In the present embodiment, the recovery unit 160 is a box body with an upper opening. The release paper 310 picked up by the paper pickup unit 130 is discarded in the recovery unit 160 in a manner of being accommodated in the recovery unit 160. In addition, the recovery unit 160 is arranged in the conveying unit 140 and can be moved by the conveying unit 140. In the present embodiment, the recovery unit 160 is arranged in an X-axis direction with the tray stage 150 (specifically, arranged on the X-axis positive direction side of the tray stage), and moves in the X-axis direction together with the tray stage 150.
[0071] It should be noted that the recovery unit 160 can be implemented by an inclined surface for receiving the release paper 310 picked up by the paper pickup unit 130, and a box connected to the inclined surface for receiving the release paper 310 flowing through the inclined surface. In this case, for example, the inclined surface moves by means of the conveying unit 140, and the box is fixedly arranged at a specific location.
[0072] The component pickup unit 190 is a mechanism that picks up the components placed on the tray 300 supplied from the component supply device 100 and places them on the component placement table 220. The component pickup unit 190 is realized by, for example, a pickup head that picks up the components and a moving mechanism that moves the pickup head. The moving mechanism is realized by, for example, a linear guide and a linear motor.
[0073] The method of holding the components by the component pickup unit 190 is not particularly limited, but in the present embodiment, as a method of picking up components by the component pickup unit 190 , a method of holding the components by vacuum adsorption is adopted.
[0074] The control device 170 is a computer that controls each device of the component supply device 100. Specifically, the control device 170 controls the tray supply unit 110, the sensor unit 120, the paper pickup unit 130, the tray conveying unit 180, and the component pickup unit 190 to make these devices perform various actions. The control device 170 is implemented by, for example, a communication interface for communicating with these devices, a non-volatile memory storing a program, a volatile memory as a temporary storage area for executing the program, an input / output port for sending and receiving signals, and a processor for executing the program. The communication interface may be a connector for connecting a communication line for wired communication, or a wireless communication circuit for wireless communication.
[0075] The control device 170 includes a detection unit 171 , a control unit 172 , and a storage unit 173 .
[0076] The detection unit 171 is a processing unit that detects the presence or absence of the release paper 310 on the tray 300 supplied from the tray supply unit 110 that supplies the tray 300 on which the components are placed and the release paper 310 covering the components. Specifically, the detection unit 171 detects the presence or absence of the release paper 310 on the tray 300 based on the detection result of the sensor unit 120. For example, the detection unit 171 determines whether the release paper 310 is on the tray 300 based on the image captured by the sensor unit 120.
[0077] The control unit 172 is a processing unit that controls the operation and operation timing of each device of the component supply device 100, such as the tray supply unit 11, the sensor unit 120, the paper pickup unit 130, the tray conveying unit 180, and the component pickup unit 190. For example, the control unit 172 controls the paper pickup unit 130 based on the detection result of the detection unit 171. Specifically, when the detection unit 171 determines that the separator paper 310 exists on the tray 300, the control unit 172 causes the paper pickup unit 130 to pick up the separator paper 310.
[0078] The processing units such as the detection unit 171 and the control unit 172 are realized by, for example, a processor, a memory, and a control program stored in the memory and executed by the processor.
[0079] The storage unit 173 is a storage device that stores various data such as the size and shape of each of the tray 300 and the release paper 310, the operation of each device, the timing of the operation, the control program executed by the processing unit, and the information used by the detection unit 171 to detect the release paper 310. The storage unit 173 is implemented by, for example, a flash memory, an HDD (Hard Disk Drive), etc.
[0080] [Specific example]
[0081] <Processing by Detection Unit>
[0082] Next, a specific example of the processing of the detection unit 171 will be described.
[0083] Figure 5 This is a diagram for explaining a specific example of the measurement position of the detection unit 171 according to the embodiment. Figure 6 It is a diagram for explaining the measurement positions of the comparative example.
[0084] As described above, for example, the detection unit 171 determines whether the release paper 310 is present on the tray 300 based on the image captured by the sensor unit 120. For example, the detection unit 171 determines the presence or absence of the release paper 310 based on the color or brightness in the image. The sensor unit 120 captures the tray 300 from above the tray 300 in a manner that the entire tray 300 is reflected.
[0085] Here, for example, if it is determined whether or not the release paper 310 is present on the tray 300 by performing image processing on the entire image generated by imaging the tray 300 by the sensor unit 120 , the amount of processing required is large.
[0086] Therefore, the detection unit 171 determines whether the release paper 310 exists, for example, based on whether the chromaticity or brightness of a specific position (also referred to as a measurement position) of the image is a predetermined value. At this time, for example, the detection unit 171 detects the presence or absence of the release paper 310 at three or more measurement positions that are arranged so as to surround the center of gravity C of the tray 300 and overlap the tray 300 when the tray 300 is viewed from above (viewed from above). For example, when the release paper 310 is detected at at least one of the three or more measurement positions, the detection unit 171 determines that the release paper 310 exists on the tray 300. On the other hand, when the release paper 310 is not detected at at least one of the three or more measurement positions, the detection unit 171 determines that the release paper 310 does not exist on the tray 300. That is, when the release paper 310 is not detected at all of the three or more measurement positions, the detection unit 171 determines that the release paper 310 does not exist on the tray 300. For example, when there are three measurement positions and the release paper 310 is detected at one of the three measurement positions but not at the remaining two measurement positions, the detection unit 171 determines that the release paper 310 is present on the tray 300 .
[0087] It should be noted that, in consideration of false detection, etc., for example, when the separator paper 310 is detected at a number of measurement positions equal to or greater than a predetermined threshold value among the three or more measurement positions, the detection unit 171 may determine that the separator paper 310 exists on the tray 300. Alternatively, for example, when the separator paper 310 is detected at a number of measurement positions equal to or greater than half of the three or more measurement positions, the detection unit 171 may determine that the separator paper 310 exists on the tray 300.
[0088] In the present embodiment, the tray 300 is square in a plan view, and the center of gravity C of the tray 300 coincides with the center of the tray 300 in a plan view.
[0089] For example, assuming that the sensor unit 120 generates Figure 5 The image of the positional relationship between the tray 300 and the release paper 310 is shown. For example, the control unit 172 controls the conveying unit 140 so that the imaging center of the sensor unit 120 coincides with the center of the tray 300. Thus, the center of the image of the sensor unit 120 coincides with the center of gravity C of the tray 300 when viewed from above. For example, the detection unit 171 determines whether the release paper 310 exists at each of the measurement positions P1, P2, and P3 in the image thus generated, which are provided so as to surround the center of gravity C of the tray 300 and overlap the tray 300 when viewed from above.
[0090] Thus, for example, with respect to Figure 6 Compared with the case where the measurement positions P4, P5 and P6 are set in a manner that does not surround the center of gravity C of the tray 300 when the tray 300 is viewed from above as shown, respectively judging whether the separation paper 310 exists, when the separation paper 310 exists on the tray 300, it can be correctly judged that the separation paper 310 exists.
[0091] It should be noted that the sensor unit 120 may generate a plurality of images including one or more measurement positions by photographing the tray 300. In this case, the detection unit 171 may detect the presence or absence of the release paper 310 on the tray 300 based on the plurality of images generated in this way.
[0092] In addition, when the sensor unit 120 is a light sensor that emits laser light and receives reflected light of the laser light, the laser light may be irradiated to each measurement position and the reflected light of the laser light may be received. In this case, the detection unit 171 may detect the presence or absence of the release paper 310 on the tray 300 based on the light reception result (e.g., light intensity) at each measurement position of the sensor unit 120.
[0093] <Processing by Control Unit>
[0094] Next, a specific example of the processing of the control unit 172 will be described.
[0095] Figure 7 to Figure 10 The figures are used to illustrate the positional relationship between the plurality of suction nozzles 131 and the release paper 310 according to the embodiment. Figure 7 to Figure 10 The diagrams schematically show the positional relationship between the tray 300, the release paper 310, and the plurality of suction nozzles 131 when viewed from above. Fig.10 In Figure 7 to Figure 9 The plurality of suction nozzles 131 are shown to be distinguished as suction nozzles 131 a , 131 b , 131 c , and 131 d , respectively.
[0096] The control unit 172 controls the paper pickup unit 130 to make the paper pickup unit 130 pick up the release paper 310 on the tray 300. For example, the paper pickup unit 130 includes a plurality of suction nozzles 131. In the present embodiment, the paper pickup unit 130 includes four suction nozzles 131, and the four suction nozzles 131 are fixed in position by the support body 132 in such a manner that the four corners of the release paper 310 can be sucked.
[0097] The detection unit 171 detects the position of the release paper 310 relative to the tray 300 based on the image generated by the sensor unit 120. The control unit 172 controls the conveying unit 140 based on the position of the release paper 310 relative to the tray 300 detected by the detection unit 171, thereby aligning the plurality of suction nozzles 131 with the release paper 310. Figure 7 As shown, the conveying unit 140 is controlled so that the four suction nozzles 131 suck the four corners of the release paper 310 .
[0098] For example, suppose Figure 8 As shown in FIG. 1 , the center of the tray 300 is greatly offset from the center of the release paper 310 when viewed from above. In such a case, for example, Fig. 9 As shown, the control unit 172 controls the conveying unit 140 based on the position of the release paper 310 relative to the tray 300 detected by the detection unit 171 , thereby aligning the plurality of suction nozzles 131 with the release paper 310 .
[0099] In this way, for example, the detection unit 171 detects the position of the isolation paper 310 relative to the tray 300, and the control unit 172 changes the relative position of the paper picking unit 130 and the tray 300 based on the position of the isolation paper 310 relative to the tray 300 detected by the detection unit 171, so that the isolation paper 310 can be picked up by the paper picking unit 130.
[0100] It should be noted that the control unit 172 may also switch whether each of the plurality of suction nozzles 131 performs suction based on the position of the separation paper 310 relative to the tray 300 detected by the detection unit 171, so that the separation paper 310 can be picked up by the paper pickup unit 130. That is, in the case where the paper pickup unit 130 is configured to change the position (suction area) of suctioning the separation paper 310 by switching whether each of the plurality of suction nozzles 131 performs suction, the control unit 172 may also change the suction area based on the detection result of the detection unit 171. For example, the plurality of suction nozzles 131 for sucking the separation paper 310 are configured to be respectively provided with valves, and whether suction is performed can be changed by the valves. The control unit 172 switches whether each of the plurality of suction nozzles 131 performs suction, for example, by controlling the valves.
[0101] For example, set Fig.10The positional relationship between the release paper 310 and the plurality of suction nozzles 131a, 131b, 131c, and 131d is shown in FIG. In such a case, for example, the control unit 172 causes the suction nozzles 131a and 131b to suck so that the suction nozzles 131a and 131b pick up the release paper 310. In such a case, for example, the control unit 172 causes the suction nozzles 131c and 131d not to suck. In this way, the control unit 172 causes only the suction nozzles 131 required to pick up the release paper 310 to operate, for example.
[0102] [Processing steps]
[0103] Next, the processing procedure of the component supply device 100 according to the embodiment will be described in detail.
[0104] Fig.11 1 is a flowchart showing the processing procedure of the component supply device 100 according to the embodiment.
[0105] First, the detection unit 171 detects the presence or absence of the release paper 310 on the tray 300 supplied from the tray supply unit 110 that supplies the tray 300 on which the components and the release paper 310 covering the components are placed (S10). For example, first, the conveying unit 140 moves the tray stage 150 toward the tray supply unit 110 (more specifically, below the tray supply unit 110). Here, the tray stage 150 receives the tray 300 from the tray supply unit 110. Next, the conveying unit 140 moves the tray stage 150 toward the camera position. The camera position is the position of the tray stage 150 when the sensor unit 120 photographs the tray 300. In the present embodiment, the camera position is below the sensor unit 120. It should be noted that, for example, the photographing direction of the sensor unit 120 and the camera position are vertically below the sensor unit 120, but when the photographing direction of the sensor unit 120 is obliquely downward, the camera position may also be obliquely below the sensor unit 120. Here, the detection unit 171 detects the presence or absence of the release paper 310 on the tray 300 supplied from the tray supply unit 110 for supplying the tray 300 on which the components and the release paper 310 covering the components are placed. Specifically, the sensor unit 120 photographs the tray 300, and the detection unit 171 determines (confirms) the presence or absence of the release paper 310 on the tray 300 based on the photographing result of the sensor unit 120.
[0106] When the detection unit 171 determines that there is a release paper 310 (Yes in S20), the control unit 172 causes the paper pickup unit 130 to pick up the release paper 310 (S30). Specifically, when the release paper 310 is detected, the conveying unit 140 moves the tray stage 150 to the paper pickup position. The paper pickup position is a position where the paper pickup unit 130 picks up the release paper 310 placed on the tray 300. Next, the paper pickup unit 130 picks up the release paper 310 on the tray 300. Next, the conveying unit 140 moves the recovery unit 160 to the paper recovery position (below the paper pickup unit 130 in this embodiment). Next, the paper pickup unit 130 discards the picked-up release paper 310 to the recovery unit 160.
[0107] When the detection unit 171 determines that the release paper 310 is not present (No in S20 ) or after step S30 , the conveying unit 140 moves the tray stage 150 to the component pickup position ( S40 ). The component pickup position is a position where the component pickup unit 190 picks up components placed on the tray 300 .
[0108] Then, for example, the component pickup unit 190 picks up the component placed on the tray 300. The picked-up component is placed on the component placement table 220. The component placed on the component placement table 220 is picked up by the component mounting device 200 and placed on the substrate 400. By repeating this process, one or more components placed on the tray 300 are placed on the substrate 400 in sequence. When the tray 300 becomes an empty tray, the conveying unit 140 moves the tray stage 150 to the tray supply position. An empty tray is a tray 300 in a state where no components are placed. The tray stage 150 returns the tray 300, which has become an empty tray, to the tray supply unit 110.
[0109] For example, by repeatedly performing the above-mentioned process, components are repeatedly supplied to the component mounting device 200 .
[0110] (Effects, etc.)
[0111] Hereinafter, the technology obtained based on the disclosure of this specification is exemplified, and the effects etc. obtained based on the exemplified technology are described.
[0112] Technology 1 is a component supply device 100, which is a component supply device for supplying components to a component installation device 200, wherein the component supply device 100 comprises: a detection unit 171, which detects the presence or absence of isolation paper 310 on a tray 300 supplied from a tray supply unit 110 that supplies a tray 300 carrying components and isolation paper 310 covering the components; and a control unit 172, which causes the paper picking unit 130 to pick up the isolation paper 310 when the detection unit 171 determines that isolation paper 310 exists on the tray 300.
[0113] Conventionally, the separator paper 310 placed on the tray 300 is removed by an operator. However, in such a method, there is a case where labor costs are increased or a work error such as turning over the tray 300 occurs, resulting in the parts being unusable. Therefore, the component supply device 100 detects the presence or absence of the separator paper 310 on the tray 300, and when the separator paper 310 is present, the separator paper 310 on the tray 300 is picked up by the paper pickup unit 130, thereby removing the separator paper 310 on the tray 300. That is, according to the component supply device 100, the separator paper 310 on the tray 300 can be automatically removed. Therefore, according to the component supply device 100, the labor costs involved in the operator removing the separator paper 310 can be reduced, and the loss of parts caused by the operator's work error can be reduced. In addition, for example, the component supply device 100 detects the presence or absence of the release paper 310 on the tray 300, and moves to the next step without performing the step of picking up the release paper 310 on the tray 300 by the paper pickup unit 130 when the release paper 310 is not present. Thus, it is possible to suppress unnecessary operation of the paper pickup unit 130. Thus, according to the component supply device 100, it is possible to suppress the cost of supplying components to the component mounting device 200, and thus it is possible to suppress a decrease in the productivity of the component mounting system 10.
[0114] Technology 2 is based on the component supply device 100 described in Technology 1. The detection unit 171 detects the presence or absence of separation paper 310 at three or more measurement positions arranged in a manner surrounding the center of gravity C of the tray 300 and overlapping with the tray 300 when the tray 300 is viewed from above, and determines that separation paper 310 exists on the tray 300 when separation paper 310 is detected at at least one of the three or more measurement positions.
[0115] When only a specific narrow measurement position is used as the detection object of the detection unit 171, if the position of the release paper 310 on the tray 300 is poor, there is a possibility that a defect that cannot be detected by the detection unit 171 occurs regardless of whether the release paper 310 exists on the tray 300. Therefore, the detection unit 171 detects the presence or absence of the release paper 310 at three or more measurement positions that are arranged so as to surround the center of gravity C of the tray 300 and overlap the tray 300 when the tray 300 is viewed from above. As a result, regardless of whether the release paper 310 exists on the tray 300, the possibility of a defect that cannot be detected by the detection unit 171 can be reduced.
[0116] Technology 3 is based on the component supply device 100 described in Technology 1 or Technology 2, and the detection unit 171 detects the position of the isolation paper 310 relative to the tray 300, and the control unit 172 changes the relative position of the paper picking unit 130 and the tray 300 in a manner that the isolation paper 310 can be picked up by the paper picking unit 130 based on the position of the isolation paper 310 relative to the tray 300 detected by the detection unit 171.
[0117] If only the release paper 310 is placed on the tray 300, the relative positional relationship between the tray 300 and the release paper 310 may deviate during the transportation of the tray 300. Therefore, the detection unit 171 detects the position of the release paper 310 relative to the tray 300. Thus, the control unit 172 can make the paper pickup unit 130 pick up the release paper 310 appropriately based on the position of the release paper 310 relative to the tray 300 detected by the detection unit 171.
[0118] It should be noted that the control unit 172 may control the paper pickup unit 130 to move, or may control the conveying unit 140 to move the tray stage 150 on which the tray 300 is placed, to change the relative position of the paper pickup unit 130 and the tray 300 .
[0119] In addition, the paper pickup unit 130 is a structure that does not move in the X-axis direction and the Y-axis direction in the above embodiment, but it can also be a structure that can move in the X-axis direction and the Y-axis direction. For example, the paper pickup unit 130 can also be implemented by making the pickup head that picks up the release paper 310 movable in the XY plane and a conveyor that can be raised and lowered in the Z-axis direction.
[0120] Technology 4 is based on the component supply device 100 described in any one of technologies 1 to 3, wherein the paper picking unit 130 has a plurality of suction nozzles 131, the detection unit 171 detects the position of the separation paper 310 relative to the tray 300, and the control unit 172 switches whether each of the plurality of suction nozzles 131 performs suction based on the position of the separation paper 310 relative to the tray 300 detected by the detection unit 171 in a manner that enables the paper picking unit 130 to pick up the separation paper 310.
[0121] Thus, the control unit 172 can make the paper pickup unit 130 appropriately pick up the release paper 310 simply by switching whether or not each of the plurality of suction nozzles 131 performs suction.
[0122] Technique 5 is the component supply device 100 described in any one of Techniques 1 to 4, wherein the component supply device 100 further includes a tray supply unit 110 .
[0123] Thus, the tray 300 can be supplied by the tray supply unit 110 included in the component supply device 100 , and the release paper 310 on the tray 300 can be appropriately removed.
[0124] Technique 6 is the component supply device 100 described in any one of Techniques 1 to 5, wherein the component supply device 100 further includes a paper pickup unit 130 .
[0125] Thus, the release paper 310 on the tray 300 can be appropriately removed by the paper pickup unit 130 included in the component supply device 100 .
[0126] Technology 7 is a component supply method for supplying components to a component mounting device 200, wherein the component supply method includes: a detection step (S20), in which the presence or absence of isolation paper 310 on a tray 300 supplied from a tray supply unit 110 is detected, and the tray supply unit 110 supplies a tray 300 carrying components and isolation paper 310 covering the components; and a control step (S40), in which when it is determined in the detection step that isolation paper 310 exists on the tray 300 (yes in S30), the paper picking unit 130 picks up the isolation paper 310.
[0127] This achieves the same effects as those of the component supply device 100 .
[0128] It should be noted that these general or specific solutions can be implemented by a system, method, integrated circuit, computer program or computer-readable CD-ROM or other recording medium, or by any combination of a system, method, integrated circuit, computer program and recording medium. For example, the present invention can also be implemented as a program that enables a computer to execute a component supply method. For example, in addition, the present invention can also be implemented as a computer-readable non-temporary recording medium storing the program.
